I To all whom it may 'ti n wi h n Be it known that we, SOLOMON LUBER and Max Emma, citizens of Poland and the United States, respectively, and residents of New York, in the counties of New York and Kings, respectively, and Stateof New York, have invented certain new and useful Improvements in Pyrophoric Igniting Devices, of which the following is a specification.

The present invention relates to ignitingdevices, and more particularly to pocket igniting-devices, including means for producingsparks by the abrasion of a pyrophone body.

In one type'of these devices, the spark-- ing element is held in engag'ement wlth a combined thumb wheel and friction disk,

that is rotated in the proper direction by the thumb of the user, to roduce a spark. This friction disk is rovi ed. with a milled peripher against w ich the sparking element is old by a spring. In order to rotate the friction disk, the-thumb is placed against the milled periphery thereof and moved toward the casing of the implement. Due to the factthat the wheel is under the action of a spring, it is very hard to turn, and its milled peripheral portion is thus apt to injure the thumb.

The main object of the present invention is to obviate these defects of the devices heretofore in use, by attaching to the cover of the casing an element, that imparts rotation tothe friction disk, when removed from the casing. -Another object of the invention is to produce a pocket igniting device of the type mentioned which is simple in construction, efiicient in operation and which can be manufactured-on a commercial scale, or inother Words one which is not so difficult to make as to be'beyond the reasonable cost of such a contrivance. I

With these and other objects in' view, which will more full appear as the nature of the invention is 'tter understood, the same consists in the combination, arra ment and. construction of parts hereinar described, pointed out in the appended claim and illustrated in the accompanying draw ings, it bein understood that many changes may be ma e in the size and proportion of' the'several tgarts and details of construce scope of the appended claim free en shown at 19, for a purpose that will ap-' without departin from the s irit or sacrific- 1ng any of the a vantages o the invention. A few of the many ossible embodiments of the invention are ilustrated in the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of a pocket igniting device constructed in accordance with the present invention; Fig. 2 is a similar elevation of g the same, showing the cover in a position to actuate the friction disk thereof; and Figs. 3 to 5, inclusive, are vertical central sections taken through modified covers.

Referring now first to Figs. 1 and 2 of the drawings, the numeral 10 indicates a closed caslng, having a reducedupper end 11, onto which fits a cover 12. The casing is provided with a wick tube 13, adapted 'to' I expose at its upper end a wick 14, that is saturated with a volatile liquid hydrocarbon. A tubular guide 15- extends substantially parallel w1th the wick tubeyits upper end forming lugs 16 in proximity to the upper end of the wick tube, and in thisguide is disposed a pyrophoric body 17, that s held by a spring (not shown) against the milled peripheral face of a friction disk 18, the latter being rotatably mounted in the lugs 16. The friction disk is mounted 'to rotate in a plane passing longitudmall through the wick tube. Thus far describe the function and operation of the elements arewell-known, so that a detailed descripfion of the same is deemed to be unnecessa - W i thin the cover 12 is disposed a blade spring 19 having a downwardly extending rou hened portion 20, abutting a ainst the mil ed eriphery of the friction isk. The

s of the spring is bent outwardly, as

pear. hereinafter. A portion of the spring, denoted by the numeral 21, rests against the inner face of the to portion of the cover, a rivet 22 passing tlirough the spring an d -the top portion of the cover, to hold the -disk in the direction of the arrow shown friction disk, so that the latter easily finds its place.

Instead of using a rivet for attaching the sprin to the cover, a lug 23 may be stamped out rom the body portion of-the spring cover of t (Fig. 3). This lug is extended throu h an aperture 24 in the cover and its free en provided with a head 25, that abuts against the outer face of the cover. j

Another method of securin the spring to the cover is illustrated in ig. 4 of the drawings, in which the spring is provided with outwardly extending projections 26, fitting into depressions 27 in the cover.

The spring may be secured to the cover by forming u on opposite portions of the latter inward y extending pro'ections 28, that bear against the spring, ig. 5).

It is to observe that, while herein several. ways of fastening the spring to the e implement are shown, others may just as well be used without departing from the invention, which lies mainly in the provision of a springy body, that bears against the friction disk and is adapted to rotate the same in the proper direction upon removal of the cover from the casing of the implement.

hat we claim is A pocket ignitin device comprising a casing havin a re uced upper end, of a removable cover fitting said reduced end, a -Wick tube in said casing adapted to expose a wick at its upper end, a friction disk mounted to rotate in a plane passing longitudinally through the wick tube and located adjacent the end of the wick tube, a sparking element held in engagement with said friction disk, and a spring attached to said cover having a roughened surface portion in abutment with said friction wheel adapted to rotate the latter upon removal of said cover from said casing. v 1
